SMTP Server

The SMTP Server page allows you to configure a Simple Mail Transfer Protocol (SMTP) server. Once you configure an SMTP server, Nessus can email HTML scan results to the list of recipients that you specify in the scan settings.

Note: You need the System Administrator role to configure Tenable Nessus settings. For more information, see Users.

The following table describes the SMTP Server settings:
